Function
Adjusts the width of the area on the
white plate (in the sub scan
direction) that is scanned for auto
shading.
The default is 5 mm. The current
setting specifies the difference from
this default.
Adjusts the magnification in the sub
scan direction for scanning. If this
value is changed, the scanner motor
speed is changed.
Use the key to toggle between +
and - before entering the value. The
specification is ± 0.5%. See
"Replacement and Adjustment -
Copy Adjustment" for details.
Displays the status of the APS
sensors and platen/DF cover sensor.
See "APS and Platen/ADF Cover
Sensor Output Display" after the SP
mode table.
Selects whether the copier
determines that the original is A5
size when the APS sensor cannot
detect the size.
If "A5 lengthwise" is selected, paper
sizes that cannot be detected by the
APS sensors are regarded as A5
lengthwise. If "Not detected" is
selected, "Cannot detect original
size" will be displayed.
This is for the designer's test
purposes.
Do not change the value.
